Sierra CV diagnosis

Hey all,

Is there an easy way to confirm a busted CV, without having to pull it out?

Broke it on a run in the Glasshouse Mts last weekend... :cry:

Cheers,

Paul

You can just tell, there are many simpltoms, clicking, crunching, rattling, a rash

us hearing deficient types just look out the window, see which tyres dragging, locking up in reverse, or not turning when booted, etc. And you can usually feel a tug on the steering in the directuion of the busted one.
Its usually the short side that breaks, tho mine has done one of each.
Its time to look at both, anyway, as they probably both need servicing..Its not real safe driving with busted cv still in place, as broken bits can grab the steering, with dire consequences...christover

Probably a silly question, but can I pull it out and drive around in 2wd till I find a new one?

Obviously have to drain diff etc -would this be ok in the short term?

I removed my broken cv, drove round for 3 weeks before I fitted another, and I did not drain the oil, and only lost a bit out thru the hub.
So it should be fine, certainly safer than leaving it in. christover

make sure you get all the broken bits/balls out, usually in the oil in bottom of hub...some very sharp, so be careful, christover

Why not unlock the hubs and leave it in 2WD

Does the same thing

How?

If the free wheeling hub is unlocked, the axle has no connection to the wheel at all, and if the transfer is in 2wd the tailshaft does not turn.

nothing to do with turning axles, cv's and tail shafts etc....the pieces broken off the cv can wedge in the knuckle and prevent steering from functioning...also broken pieces can grab at the knuckle casings causing damage, making seals not fit well etc....most people I know who have driven with busted cv still in vehicle have had to stop and remove it, due to sudden loss of steering.....you can be lucky and have no bits actually fall out, but I don't like to risk it..with hubs unlocked, yes your right, nothing is spinning, its just a steering issue....

Broke mine yesterday and yes you do lose steering and yes your better off removing it.
